| Abstract: | Myrtenol was synthesized form 2,10-epoxypinane as raw material by liquid phase isomerization in the presence of ammonium salt catalysts.The influence of catalysts,solvents,reaction temperature and reaction time on the product distributions was investigated emphatically.Experimental results indicated that myrtenol can be obtained with 84.1% conversion of 2,10-epoxypinane and 65.7% selection of myrtenol via liquid phase isomerization of 2,10-epoxypinane catalyzed by NH4NO3 in 1,1,2-trichloroethane at reflux condition for 4 h. |
| Keywords: | myrtenol 2 10-epoxypinane acid catalyst liquid-phase rearrangement |
